Official abstract text for this publication.
A range image obtaining system for a track includes a laser slit light source disposed within a plane perpendicular to a tread of a rail and emits laser slit light within the plane; a two-dimensional image imaging device which is disposed to have an angle with respect to the plane perpendicular to the tread of the rail and obtains a light sectioning image generated from the laser slit light; and an image signal processing device for generating a range image based on a distance from the two-dimensional image imaging device based on the light sectioning image.
Opening claim text (preview).
What is claimed is: 1. A range image obtaining system for a track comprising: a laser slit light source disposed within a plane perpendicular to a tread of a rail and emits laser slit light within the plane; a two-dimensional image imaging device which is disposed to have an angle with respect to the plane perpendicular to the tread of the rail and obtains from a running railcar a plurality of light sectioning images generated from the laser slit light; an image signal proces…
